Abstract: An expansion reinforcing plate and a paving method therefor, the expansion reinforcing plate comprising plates and an elastic inserting strip assembling structure; the elastic inserting strip assembling structure comprises expansion reinforcing connecting strips A (1), expansion reinforcing connecting strips B (2) and expansion reinforcing connecting strip assembling groove structures (3); the expansion reinforcing connecting strips A (1) are inserted into the expansion reinforcing connecting strip assembling groove structures (3) of two adjacent plates; the expansion reinforcing connecting strips A (1) of every two adjacent plates are jointly connected with the expansion reinforcing connecting strips B (2); the expansion reinforcing connecting strips B (2) make contact with the expansion reinforcing connecting strips A (1) on the two sides for reaction, so that the expansion reinforcing connecting strips A (1) and the expansion reinforcing connecting strips B (2) expand and are fixedly connected, and then th

Abstract: The present invention provides a self-enhancement plastic profile and a production method thereof. The self-enhancement plastic profile is made by co-extrusion a substrate resin and a PBT resin containing fiber glass. The production method of the self-enhancement plastic profile is that: melting and co-extrusion of the substrate resin and the PBT resin containing fiber glass. Infrastructures comprise a main engine and an auxiliary engine vertically arranged to the main engine. The main engine processes the PVC substrate (1), the auxiliary engine processes an enhancement bar (2) of the PBT resin containing fiberglass, the raw materials are extruded by the main engine and the auxiliary engine at the same and the extrudate is pre-profiled, and subjected to cold cutting and sized. The enhancement bar (2) is made by blending the fiberglass with the polybutylene terephthalate (PBT) plastic. The self-enhancement plastic profile has advantages of simple, convenient and quick installation and convenient to produce.
